Abstract (en)

A water-swellable composition comprising 80-95% by weight hydrocarbon oil, 3-7.5% by weight styrene-(ethylene-propylene) di-block copolymer, 5-15% by weight water-swellable polymer, 1-5% by weight surfactant and 2-10% by weight gelling agent. The water-swellable composition exhibits excellent anti-slump properties and no oil separation. The water-swellable composition may be used as a filler for sheathed cables.
